The catalytic enantioselective Mannich reaction promoted by chiral palladium complexes is described. The treatment of alpha-fluoro-beta-ketoesters with N-Boc-aldimines under mild reaction conditions afforded the corresponding beta-aminated alpha-fluoro-beta-ketoesters with excellent enantioselectivities (up to 99% ee).

The catalytic enantioselective Mannich reaction promoted by chiral bifunctional organocatalysts is described. The treatment of α-fluoro-β-keto esters with N-Boc aldimines under mild reaction conditions afforded the corresponding β-aminated α-fluoro-β-keto esters with excellent enantioselectivities (up to 98% ee).
